| titleOfInvention | Get rid of device of hydrolysis system impurity and retrieve hydrazine hydrate and acetone |
| abstract | The utility model provides a get rid of device of system's of hydrolysising impurity and recovery hydrazine hydrate and acetone, including one, the second grade knockout tower cauldron, the condenser, the feed inlet of first grade knockout tower cauldron is used for being connected with the system hydrolysis tower, the cauldron bottom of first grade knockout tower cauldron is through first pipeline to the feed of second grade knockout tower cauldron, be equipped with the charge-in pump on this first pipeline, the cauldron top of first grade knockout tower cauldron links to each other through the material import of second pipeline with the condenser, the cauldron top of second grade knockout tower cauldron is through the fourth pipeline to the feed of first grade knockout tower cauldron, the upper reaches end of a discharging pipe is connected with the cauldron bottom of second grade knockout tower cauldron, be equipped with the discharge pump on this discharging pipe, the low reaches end and the hydrazine hydrate storage. The utility model has the advantages of being simple in structure and convenient in operation, with system parallel operation of hydrolysising, extract the hydrolysate in succession and get rid of impurity isopropyl hydrazine to retrieve hydrazine hydrate and acetone, make the system impurity content of hydrolysising control below 6% (w/v), realize the steady operation of the system of hydrolysising. |
